submitted to senior management for final approval. The
agreement includes outsourcing support of Windows and
UNIX server administration and network management to a
third party.

Servers will be relocated to the outsourcer’s facility that is


located in another country, and connectivity will be
established using the Internet. Operating system software
will be upgraded on a semiannual basis, but it will not be
escrowed. All requests for addition or deletion of user
accounts will be processed within three business days.

A right to audit clause is in place, but 24-hour notice is


required prior to an onsite visit. If the outsourcer is found to
be in violation of any of the terms or conditions of the
contract, it will have 10 business days to correct the
deficiency. The outsourcer does not have an IS auditor, but
